+*** Description
+
+The historical LastFM import duplicated a number of scrobbles. The importer
+itself was not fixed, but a `dedup_scrobbles` management command now removes
+duplicate scrobbles where the start timestamp, end timestamp, and media
+scrobbled are identical. Run it dry (default) to report duplicates, or with
+`--commit` to delete them. A `--media-type` filter limits the scan.
 ** DONE [#A] Write a script to check for raw mopidy vs found track discrepancies :tracks:metadata:
